Dysentery

Make a strong tea of sweet gum bark ; to a pint, add a gill of good brandy, half an ounce of laudanum, a little loaf sugar to make it palatable. Take a teaspoonful every hour until the effect of the laudanum is apparent, then at longer intervals, until the disease abates.

A very good and simple remedy, if used when the first symptoms appear, is : Give an adult five drops of spirits of turpentine
in a teaspoonful of sweet milk. Repeat, if necessary. Give a child according to age.

Another remedy : A teacup half full of apple vinegar. Dissolve as much salt in it as it will hold, leaving a little at the bottom. Pour boiling water upon the solution until the cup is three-fourths full. Scald it, and remove the scum. Take a tablespoonful three times a day.
